r-markdown

问题 I'm having trouble with figure captions in html documents generated using R Markdown. If I don't specify the fig.retina option, or if I set it to 1, the output document has a figure caption. If I set it to a value that isn't 1, however, the future caption is missing but the text for it is present as the alt text for the figure. How can I keep the figure captions? An example: --- title: "Example" output: html_document: fig_caption: yes fig_retina: 2 --- Text text text ```{r fig.cap="Figure 1.

问题 In my rmarkdown document, I want to include plots side by side to save space. For example, I want to include: plot(rnorm(100)) hist(runif(100)) or plot(rnorm(100)) hist(runif(100)) I don't really care if there is one caption for both subplots or one caption for each subplot. I just really want to include figures side by side and have some way to refer to them (Figure 1, etc). Does anyone have suggestions? I have this in my header: header-includes: - \usepackage{subfig} When I don't have "fig

问题 I am trying to knit a flexdashboard to an html file. My flexdashboard includes leaflet maps. The knit.md file compiles correctly. At the last stage, converting the knit.md to an html file, I get an error. Apparently leaflet is looking for html dependencies in the R 3.3.2 folder, rather than the R 3.4.2 folder. I originally built this flexdashboard months ago on a different machine on which I had R 3.3.2 (although I was using 3.4.1 I believe to build this). So the problem appears to be that

问题 I have numerous huxtable tables in my rmarkdown. I'd like to caption them using bookdown. So far I've been unable to do this using the bookdown instructions for "other R packages to generate tables" (see URL above). Here's an example which follows the instructions in this answer: --- title: "huxtable-mwe" site: bookdown::bookdown_site output: bookdown::html_book documentclass: book --- ```{r setup, include=FALSE} knitr::opts_chunk$set(echo = TRUE) library(huxtable) library(magrittr) ``` See

问题 I was trying to produce a PDF file with the knitr in RStudio but I encountered a problem. I have read a lot of solutions found on stack overflow and google but they are not very helpful.

问题 I'm using ioslides (rmarkdwon) in RStudio to create the presentation from R. I would like to add the logo, but only to the first slide (main) which renders this information: --- title: "Presentation" author: "Tom Hanks" output: ioslides_presentation logo: logo.jpg --- I don't want the logo in the bottom-left footer of each slide. Can anyone tell me how to switch it off? 回答1: You could modify the ioslide template to remove the repetition of the logo on each page. Download the template on the
